Oscar is (at the beginning of the film) part of Harry Stamper's crew on an oil rig in the South China Sea. When an asteroid threatens humanity's existence, he is chosen as a member of the mission crew because he is, Grace Stamper says, spacy, but an absolutely brilliant geologist . The teams are sent into space to land on the asteroid, drill into it, and plant a bomb to blow it up.Oscar owns a horse ranch outside of El Paso and is presumably a very good rider. Like many of his colleagues, he seems extremely wary of the law - he is seen riding away from government helicopters when they track him down with the offer of joining his colleagues in space. This may suggest that either he has broken the law or dislikes the police. However, he may simply have attempted a getaway because he was not aware of who was in the helicopters and thus feared for his life.Out of those asked to go into space, Oscar is the most enthused. Although quiet at first, he calls the situation historic and it's clear that he is excited at the prospect of being seen as heroic.In the requests the men make to the government, Oscar asks if outstanding parking tickets can be wiped from his record (fifty-six tickets in seven states). From this, we know both that Oscar is well-travelled (at least in the United States) and that he must have little regard for certain laws.It's possible that Oscar watches a lot of television or/and has a very active imagination. We see him playing with NASA's equipment on more than one occasion - first with defibrillators when pretending to be a doctor saving a life, then with controls when pretending to send off rockets. This could also be reflective of his age, as he is one of the younger drillers.Despite his excitement, he may be interpreted as the person who displays the most nerves about going into space. He asks NASA's Executive Director, Dan Truman, about the environment on the asteroid, and afterwards adds, That's all you gotta say - scariest environment imaginable . Then when he is being strapped into the shuttle, he displays a mixture of fear and excitement (but expresses not knowing which emotion he feels the most). He asks to be strapped in particularly tightly, due to a fear of falling out.We know he is a man of faith, because when the crew are given time off on the day before the mission, Oscar spends it praying in a religious building. However, he may not follow a strict religion, as he later (happily) attends a club in which there are dancing, half-naked women.Oscar begins the mission on Shuttle Independence with Air Force Colonel Davis, NASA pilot Tucker, and munitions specialist Halsey, as well as his usual colleagues AJ, Bear, and Noonan.We see a more awkward side to him when both shuttles dock at the Russian Space Station. Upon meeting Russian cosmonaut Lev Andropov, Oscar begins to talk about Russia's troubles. This could portray him as a bad conversationalist and as someone who becomes awkward in certain social situations.There are a few instances in the film where Oscar expresses or demonstrates difficulty in controlling his emotions. One is his defence of Grace Stamper's actions to her father, in which he explains that he (Oscar) knows what it's like to have hormones pulling you in...a thousand different directions ; another is the aforementioned confusion over whether he is experiencing more fear or more excitement; and the third is during the shuttles' slingshot manoeuvres around the moon, when one moment Oscar is assuring the others that everything is normal and the next he is yelling about how it is much worse than normal.Oscar sadly loses his life after Shuttle Independence is hit by debris from the asteroid, which causes it to lose its main thrusters and crash on the rock. It appears as though he is not able to fit on his helmet and get into the cargo bay before the impact. (However, when his body is found by AJ, Oscar's helmet is on, suggesting he secured it at the last moment.) Show less «
